Application filed June 8,1905. Serial No. 264,361.

' T at whom it may concern:

' This invention relates to new and useful improvements in stump-pullingmachines.

The object of the invention is to provide a base for the machine, saidbase being so constructed as to permit the machine to be easily movedover rough timber-land and among stumps without easily upsetting thesame.

Another object is to provide an improved means for securing theinner'end of the sweep to the winding-drum and means for supporting andcarrying the outer end of the same over the pull-rope and over roots andstumps.

A further object is to provide means for throwing the winding-drum outof gear and to provide means for detachably securing the end of thepull-rope to the drum, so that the rope will be guided to the center ofthe drum, and means for increasing the power of the machine.

With these and other objects in view the invention consists of certainnovel features of construction, combination, and arrangement of parts,as will be hereinafter described and claimed.

In the accompanying drawings, Figure 1 is a side elevation of the devicearranged in operative position. Fig. 2 is a top plan view of the same,showing the parts arranged to increase the power of the machine. Fig. 3is a vertical sectional view with the parts in operative position. Fig.4 is a similarview showing the sweep-rest elevated and out of gear withthe winding-drum. Fig. 5 is a similar view taken at right angles toFigs. 3 and 4, and Fig. 6 is a plan view of the platform and base withthe machine removed.

Referring more particularly to the drawings, 1 denotes the platform ofthe machine, which is constructed of two timbers 2, which are preferablyround logs. The timbers 2 are bolted together at one end, as shown at 3,the opposite ends of the same diverging to form a V-shaped arrangement.To the platform timbers 2, substantially midway between the ends of thesame and preferably at right angles to one of said timbers, is bolted orotherwise secured a base plate or bar 4. On one end of the bar 4 isformed an anchoring-hook 5, to which is adapted to be connected ananchor-rope 6, by which the machine is secured to a stump or other formof anchor. On the upper side of the base-bar 4 is arranged anupwardlyprojecting stub-axle 7, on which is revolubly mounted a groovedor channeled winding-drum 8. On the under side of the winding-drum 8 isformed an annular series of ratchet-teeth 9, with which is adapted to beengaged a holding-pawl 10, said pawl being pivotally mounted upon theside of the basebar 4, as shown. In the upper portion of thewinding-drum 8 is formed a rectangular recess 12, and on the top portionof the drum adjacent to the edge of the same is formed apull-rope-attaching hook 13, which communicates with a guide-passage bywhich said pull-rope is guided or conducted to the center of the windin-drum.

Arranged in t e recess 12 is a centrallydisposed upwardly-projectingshaft 14, the lower end of which is seated in an aperture formed in thestub-axle 7. On the shaft 14 is slidably mounted a sweep-rest 15, on thelower end of which is formed a rectangular projection 17, which isadapted to seat into the rectangular recess 12 formed in the upper sideof the winding-drum, thereby securing said sweep-rest to the drum. Inthe sweeprest 15 is formed a horizontal transversely-disposed passage18, forming a seat to receive the inner end of a sweep 19, said innerend of the sweep being provided with a verticallydisposed aperture 20,through. which the shaft 14 passes, thereby securing said sweep in therest.

On the upper end of the shaft 14 is mounted a collar 21, on which isformed a pair of laterally-projecting ears or lugs 22, between which ispivoted the inner offset end 23 of a lifting-lever 24. To said inner endof the lever 24 is also connected a link 25, which is adapted to engagea hook or projection 26 formed on the upper end of the sweep-rest. Byproviding the lever 24 the sweep-rest may be raised and lowered on theshaft 14 to move the projection 17 on the lower end thereof out of andinto engagement with the recess 12, formed in said winding drum, therebythrowing the sweep-rest out and into engagement with the winding drum.The operation of the lever 24 is clearly shown in Figs. 3 and 4 of thedrawings.

On the opposite-end of the base 4from the anchor hook 5 is j ournaled ashortenersheave 27, around which the pull-rope 28 is adapted to be woundafter passing through a snatch-block 29, whereby said pull-rope may bequickly shortened and the slack in the same taken up. Connected to thesnatchblock 29 is a hitch-rope 30, the opposite end of which is adaptedto be connected with one or more stumps to be extracted, or, if desired,the hitch-rope 30 may be passed around a second snatch-block 31, thefree end of the hitch-rope 30 being secured to a rope-shortener orgrooved pulley 32, secured to the side of the base-bar 4, as shown inFigs 3, 4, and 6. To the second snatch-block 31 is secured a hitch-rope33, the opposite end of which is attached to the stump to be pulled. Byproviding one or more snatch-blocks and additional pull-ropes the poweror pulling capacity of the machine will be increased.

In order that the outer end of the sweep 19 may be supported to carrythe same over the pull-rope 28 and stumps or obstructions that may liein the path thereof, a pole 34 is rigidly secured to the outer end ofthe sweep. Said pole is preferably bolted to the under side of said endand from thence extends forwardly between the draft-animals and issecured to the neck-yoke, thus forming a runner to carry the end of thesweep in an elevated position.

By providing a platform constructed as herein shown and described themachine may be more readily transported from one stump to another overrough timber-land and stumps without danger of upsetting the same andwhen the machine is in use will form a firm support or rest for theoperating mechanism of the machine. By providing a sweep-rest adapted tobe moved into and out of engagement with the winding-drum said drum maybe thrown into and out of gear, thus providing for an independentmovement of the drum without moving the sweep or sweep-rest A stumppuller constructed as herein shown and described will be found to becomplete and eflicient in all its details.

From the fore oing description, taken in connection with t eaccompanying drawings, the construction and operation of the inventionwill be readily understood without requiring a more extendedexplanation.

Various changes in the form, proportion, and the minor details ofconstruction may be resorted to without departing from the principle orsacrificing any of the advantages of this invention.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. In a stump puller, the combination with a V-shaped platform, of abase secured to said platform, an upwardly projecting stub-axle securedto said base, a winding drum revolubly mounted on said axle, a sweepsupport having a horizontally disposed opening to form a sweepseat, arectangular projection formed on the lower end of said support to engagea similarly-shaped recess in said winding-drum, a sweep secured in saidopening, a centrally-disposed shaft extending through said sweepsupport, and winding-drum and into said stub-axle, a lever connected tothe upper end of said shaft, and means whereby said lever is connectedwith said sweep-support to raise and lower the same out of and intoengagement with said winding-drum, substantially as described.
